Description

Technical Field

[0001] The present application relates to the field of electronic communications, and in particular to a network transmission method, device, electronic device and storage medium. Background Art

[0002] With the development of computer technology, more and more devices are connected to the network to communicate with each other. In the network, devices usually use the Address Resolution Protocol (ARP) to obtain the physical (MAC) addresses of other devices in the same network. However, when a host on a network sends to another host on the same network segment but not on the same physical network, they cannot communicate directly because their Internet Protocol (IP) addresses are routable, but the physical addresses are not.

[0003] In the case where the above host devices cannot communicate directly, proxy ARP can play a role. Traditional related technologies require users to plan the ARP proxy mode in advance in a specific network planning scenario, and require that all hosts on the same physical network can only configure one ARP proxy mode, so that the hosts on the same network can communicate with each other even if they are not on the same physical network. However, in related technologies, data forwarding between each host requires the participation of a proxy device, which can easily cause performance bottlenecks, low forwarding performance, waste resources, and cannot adapt to different network scenarios, and has poor flexibility.

[0004] Currently, no effective solution has been proposed for the problem of how to dynamically enable a suitable ARP proxy mode in the related art. Summary of the invention

[0055] This embodiment provides a network transmission method. Figure 2 is a flow chart of a network transmission method according to an embodiment of the present application, such as Figure 2 As shown, the process includes the following steps:

[0056] Step S201, obtaining a cache entry of the intercommunication to be detected in the cache table of the intercommunication between hosts to be detected.

[0057] Read the intercommunication cache entry to be detected in the host intercommunication cache table, and obtain the target information corresponding to the entry. The target information may include the corresponding source device address information, destination device address information, entry status information, proxy mode information, the number of ARP requests received during the intercommunication detection cycle, cache entry duration information, and preset aging duration information.

[0058] Step S202: Determine the number of cache address resolution protocol requests corresponding to each intercommunication cache entry to be detected within the intercommunication detection cycle time.

[0059] The address resolution protocol request received by the intercommunication cache entry to be detected is determined as a cached address resolution protocol request (cached ARP request). The number of cached ARP requests received by each intercommunication cache entry to be detected within the intercommunication detection cycle is determined.

[0060] Step S203, when the number of cached ARP requests is greater than a preset number threshold, a free ARP message corresponding to the intercommunication cache entry to be detected is generated, and whether multiple devices to be detected can intercommunicate through a proxy is determined based on the free ARP message.

[0061] When the number of cached ARP requests exceeds the preset number threshold, it means that the multiple devices to be detected corresponding to the table entry cannot communicate directly, and it is necessary to trigger the reachability detection process between the proxy device and the device to be detected to determine whether the multiple devices to be detected can communicate with each other indirectly through the proxy device. If so, the table item status information of the table item corresponding to the device to be detected is indirectly reachable. Specifically, a free address resolution protocol message corresponding to the intercommunication cache table item to be detected can be generated, and whether the multiple devices to be detected can communicate with each other through the proxy can be determined based on the free address resolution protocol message. In addition, when the number of cached ARP requests does not exceed the preset number threshold, it means that the multiple devices to be detected are already intercommunication, and there is no need to start the proxy. The table item status information of the intercommunication cache table item to be detected can be updated to a directly reachable state.

[0062] Step S204: when multiple devices to be detected can communicate with each other through a proxy, enable the target proxy mode.

[0063] Based on the reachability detection process between the proxy device and the device to be detected, when it is determined that multiple devices to be detected can communicate with each other through the proxy, the target proxy mode is enabled to ensure the communication and transmission requirements between the multiple devices to be detected.

[0064] Through the above steps, the embodiment of the present application obtains the intercommunication cache table items to be detected in the intercommunication cache table of the host to be detected, and determines the number of cache address resolution protocol requests corresponding to each intercommunication cache table item to be detected within the intercommunication detection cycle time. When the number of cache address resolution protocol requests is greater than the preset number threshold, it indicates that the devices to be detected cannot communicate directly with each other, and it is necessary to further detect whether they can communicate indirectly through the proxy, thereby generating a free address resolution protocol message corresponding to the intercommunication cache table item to be detected, and determining whether multiple devices to be detected can communicate indirectly based on the free address resolution protocol message. When multiple devices to be detected can communicate indirectly with each other, the target proxy mode is enabled to avoid starting the proxy for all forwardings, reduce forwarding pressure, solve the problem of how to dynamically enable a suitable address resolution protocol proxy mode in the related technology, do not need to plan the network scenario in advance, can dynamically perceive the network topology, start and stop the proxy according to demand, improve forwarding performance, alleviate network transmission pressure, avoid waste of resources, and have high flexibility.

[0065] In some embodiments, step S203 includes:

[0066] Step S2031: When the number of cached ARP requests is greater than a preset number threshold, a first free ARP message and a second free ARP message are generated.

[0067] When the number of cached address resolution protocol requests is greater than a preset number threshold, a first free address resolution protocol message (first free ARP message) and a second free address resolution protocol message (second free ARP message) are generated and sent to detect whether an ARP response from the device to be detected can be received.

[0068] Step S2032: Send a first free address resolution protocol message to the first device to be detected to determine whether a first address resolution protocol response message sent by the first device to be detected is received.

[0069] The multiple devices to be detected include a first device to be detected, and a first free ARP message is sent to the first device to be detected to determine whether a first address resolution protocol reply message (first ARP reply message) sent by the first device to be detected is received. If the first ARP reply message can be received, it means that the first device to be detected and the proxy device can communicate with each other.

[0070] Step S2033: Send a second free address resolution protocol message to the second device to be detected to determine whether a second address resolution protocol response message sent by the second device to be detected is received.

[0071] The plurality of devices to be detected include a second device to be detected, and a second free ARP message is sent to the second device to be detected to determine whether a second address resolution protocol reply message (second ARP reply message) sent by the second device to be detected is received. If the second ARP reply message can be received, it means that the second device to be detected and the proxy device can communicate with each other.

[0072] Step S2034: upon receiving the first address resolution protocol response message and the second address resolution protocol response message, determining that the first device to be detected and the second device to be detected can communicate with each other through the proxy.

[0073] When the first address resolution protocol response message and the second address resolution protocol response message are received, it indicates that the first device to be detected, the second device to be detected and the proxy device can communicate with each other. Therefore, it is determined that the first device to be detected and the second device to be detected can forward data through the proxy device, that is, they can communicate with each other, and the table status information of the corresponding table entry is indirectly reachable.

[0074] Through the above steps, when the devices to be detected cannot communicate directly with each other, the embodiment of the present application triggers the proxy device to perform reachability detection and constructs a free ARP message to determine whether the device to be detected and the proxy device are interoperable, thereby further confirming whether the devices to be detected can communicate with each other indirectly, which has high feasibility.

[0075] In some embodiments, step S201 includes:

[0076] Step S2011, obtaining the first intercommunication cache table entry in the host intercommunication cache table to be detected, and determining the cache table entry duration corresponding to each first intercommunication cache table entry.

[0077] The first intercommunication cache entries are all entries in the intercommunication cache table of the host to be detected, and the cache entry duration corresponding to each first intercommunication cache entry is determined.

[0078] Step S2012: determine the first intercommunication cache entry whose corresponding cache entry duration is less than the preset aging duration as the second intercommunication cache entry.

[0079] When the cache entry duration corresponding to the first intercommunication cache entry is less than the preset aging duration, it indicates that the entry was established relatively recently and has not yet aged, so it is determined as the second intercommunication cache entry and is retained.

[0080] Step S2013: Acquire entry state information corresponding to the second intercommunication cache entry, and determine the second intercommunication cache entry whose corresponding entry state information is in a to-be-detected state as the to-be-detected intercommunication cache entry.

[0081] The entry state information corresponding to the second intercommunication cache entry is obtained. When the entry state information is in a to-be-detected state, it indicates that the intercommunication state of the host device corresponding to the second intercommunication cache entry is unknown and further detection is required. Therefore, the second intercommunication cache entry is determined as an to-be-detected intercommunication cache entry.

[0082] Through the above steps, the embodiment of the present application introduces an aging mechanism and filters out entries whose entry status information is not in the state to be detected, so that intercommunication detection between corresponding devices is performed only on the intercommunication cache entries to be detected, making the detection more targeted, efficient and feasible.

[0083] In some embodiments, after step S2011, the method further includes:

[0084] Step S2111: Delete the first intercommunication cache entry whose corresponding cache entry duration is greater than or equal to the preset aging duration.

[0085] When the cache entry duration of the first intercommunication cache entry is greater than or equal to the preset aging duration, it indicates that the entry was established for a long time and the preset aging time has been reached, and the first intercommunication cache entry is deleted.

[0086] Through the above steps, the embodiment of the present application deletes the intercommunication cache entries whose cache entries have lasted longer than the preset aging time, thereby further saving resources and improving efficiency.

[0087] In some embodiments, step S204 includes:

[0088] Step S2041: when the Internet Protocol addresses of multiple devices to be detected are in the same network segment, enable the local proxy mode.

[0089] Step S2042: when the Internet Protocol addresses of the multiple devices to be detected are not in the same network segment, enable the common proxy mode.

[0090] When it is determined that multiple devices to be detected can communicate with each other through a proxy device, it is further determined whether the IP addresses of the intercommunication devices to be detected are in the same network segment. If they are in the same network segment, the ARP local proxy mode is enabled, otherwise the ARP normal proxy mode is enabled. In addition, if no ARP reply message is received, it means that multiple devices to be detected cannot forward data through the proxy device and cannot communicate with each other through the proxy. At this time, the corresponding cache entry for intercommunication to be detected is deleted. It is worth mentioning that in the communication process of the embodiment of the present application, the corresponding table entry status information can also be obtained according to the received ARP request message, and the host intercommunication cache table is matched. If it cannot be obtained, no processing is performed, otherwise, different processing is performed according to different information. When the table entry status information is in a directly reachable state, the proxy device does not need to do any processing; when the table entry status information is in an indirectly reachable state, corresponding processing is performed according to the ARP proxy mode.

[0091] Through the above steps, the embodiment of the present application verifies whether multiple devices to be detected belong to the same network segment to confirm whether the corresponding ARP general proxy mode or ARP local proxy mode is turned on, which is accurate and feasible, and improves forwarding robustness.

[0092] This embodiment also provides a network transmission method. Figure 3 is a flow chart of another network transmission method according to an embodiment of the present application. Figure 3 As shown, the process further includes the following steps based on the steps in the above embodiment:

[0093] Step S301: acquiring a listening address resolution protocol message and an initial host intercommunication cache table, and updating the initial host intercommunication cache table according to the listening address resolution protocol message.

[0094] In the embodiment of the present application, the ARP messages in the network link can also be monitored in real time, and the received different types of monitored ARP messages can be processed accordingly to update the initial host intercommunication cache table.

[0095] Step S302: determine the updated initial host intercommunication cache table as the host intercommunication cache table to be detected.

[0096] The initial host intercommunication cache table is dynamically updated in real time, and the updated initial host intercommunication cache table is determined as the host intercommunication cache table to be detected.

[0097] Through the above steps, the embodiment of the present application monitors the ARP interaction information between the devices to be detected in the network in real time, thereby updating the initial host intercommunication cache table to determine the host intercommunication cache table to be detected, and can dynamically perceive the network topology with strong real-time performance.

[0098] In some embodiments, step S301 includes:

[0099] Step S3011, when the monitored ARP message is a request ARP message, determine whether the initial host intercommunication cache table contains a target monitoring table entry according to the source Internet Protocol address and the destination Internet Protocol address corresponding to the monitored ARP message.

[0100] In the case where the monitored ARP message is a request ARP message, the corresponding target monitoring table entry is determined according to the source Internet Protocol address (source IP address) and the destination Internet Protocol address (destination IP address) corresponding to the monitored ARP message. Among them, the source device address information of the target monitoring table entry is the source IP address corresponding to the monitored ARP message, and the destination device address information of the target monitoring table entry is the destination IP address corresponding to the monitored ARP message. Further, it is checked whether the target monitoring table entry is included in the initial host intercommunication cache table.

[0101] Step S3012: when the initial host intercommunication cache table includes the target monitoring entry, the entry state information corresponding to the target monitoring entry is determined as a to-be-detected state.

[0102] The state to be detected may be an update state. When the initial host intercommunication cache table includes a target monitoring entry, the entry state information corresponding to the target monitoring entry is determined as an update state.

[0103] Step S3013: if the initial host intercommunication cache table does not contain the target monitoring entry, a target monitoring entry is generated in the initial host intercommunication cache table, and the entry state information corresponding to the target monitoring entry is determined as a pending detection state.

[0104] The state to be detected may be an unknown state. When the initial host intercommunication cache table does not contain a target monitoring entry, a target monitoring entry is generated in the initial host intercommunication cache table, and the entry state information corresponding to the target monitoring entry is determined to be an unknown state.

[0105] In addition, when the listening address resolution protocol message is a reply address resolution protocol message, it is determined whether the initial host intercommunication cache table contains a corresponding reachable listening table entry according to the source Internet Protocol address and the destination Internet Protocol address corresponding to the listening address resolution protocol message. If not, a reachable listening table entry is pre-built and its table entry state information is determined to be a directly reachable state; if it exists, the table entry state information of the corresponding reachable listening table entry is directly updated to be a directly reachable state.

[0106] Through the above steps, the embodiment of the present application further enhances the dynamic perception capability and real-time performance of the solution by pre-building table entries between the devices to be detected while monitoring, and parsing ARP packets to perceive in advance whether the devices to be detected are directly reachable.

[0107] The embodiments of the present application are described and illustrated below through preferred embodiments.

[0108] Figure 4 1 is a flow chart of a network transmission method according to a preferred embodiment of the present application. Figure 4 As shown, the network transmission method includes the following steps:

[0109] Step S401: obtaining a cache entry of the intercommunication cache to be detected in the host intercommunication cache table to be detected.

[0110] Step S402: Determine the number of cache address resolution protocol requests corresponding to each intercommunication cache entry to be detected within the intercommunication detection cycle.

[0111] Step S403, when the number of cached ARP requests is greater than a preset number threshold, a free ARP message corresponding to the intercommunication cache entry to be detected is generated, and whether multiple devices to be detected can intercommunicate through a proxy is determined based on the free ARP message.

[0112] Step S404: when multiple devices to be detected can communicate with each other through a proxy and the Internet Protocol addresses of the multiple devices to be detected are in the same network segment, enable the local proxy mode.

[0113] Step S405 , when multiple devices to be detected can communicate with each other through the proxy and the Internet Protocol addresses of the multiple devices to be detected are not in the same network segment, enable the common proxy mode.

[0114] It should be noted that the steps shown in the above process or the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.
